"Ketron has only AJ for support in US. However *he is easier to reach than anyone at Korg*, although Paulo monitors the Korg forum and is helpful. You can't pick up the phone and call him though.", says Don M. above!

In addition to myself, please note that you now also do have VERY knowledgable KETRON dealers like Frank V. @ Audiworks, Curt @ IMMusic, Dan O, Jay Fox (to name but a few) here in the USA who are but a phone call or email away and who are a lot faster and easier to reach than most other support teams of other manufacturers.

For those who need to have product support, a guide and friend AFTER the sale is over, I think Don M. has phrased it better above.
